Resumen
[EN] Trichoderma is a genus of fungi used for the biological control of plant diseases and a large
number of its bio-formulates are available in the market. However, its efficacy under field conditions
remains unclear, especially for the protection of grapevine plants against Grapevine Trunk Diseases
(GTDs). These diseases are caused by a complex of fungal pathogens whose main point of entrance
into the affected plants is through pruning wounds. In this research, different Trichoderma native
strains have been evaluated according to their ability to grow at different temperatures and their
capacity to colonize pruning wounds in adverse climatic conditions. Strains from section Trichoderma
have adapted to cooler conditions. On the other hand, strains from clade Harzianum/Virens grow
at higher temperatures. However, differences can also be found between strains inside the same
clade/section. Native strains were able to colonize more than 70% of vine pruning wounds in winter
conditions. The Trichoderma strain T154 showed a significantly higher re-isolation degree from vine
plants and its concentration was optimized for spraying onto vine plants. In conclusion, Trichoderma
native strains are better adapted to survive in a changing environment, and they could give better
protection to grapevine plants in co-evolution with each specific vineyard
